DEVICE FOR OPERATING THE PUTIVIPS OF A GROUP OFOILWELLS.

SPECIFICATION forming part of Letters Patent No. 366,125, dated July 5, 1887.

Application filed June 1-l, 1886. Serial No; 205,056. (No model.)

To @ZZ whom, it may concern.-

Beit known that I, HARRIsoN H. N oYns, a citizen of the UnitedStates, and a resident of Pleasantville, in the county of Venango and State of Pennsylvania, have invented a'new and Improved Device for lOperating the Pumps of a Group of Oil-lVells, of which the following is a specification.

Myinvention relates to that class of devices in which the motion is transmitted to each of a series of pumps of a group from one engine or source of power, the wells being balanced so as to require the minimum of power, my object being to construct the transmitter so that it will work cheaply and effectively, and so that it may be located either centrally or entirely to one side of the group, as may be convenient for other purposes. This object I accomplish by the mechanism illustrated in the accompanying drawings, in which- Figure lis aside view of my device; Fig. 2, a top or plan view, and Fig. 3 a View ou line 00g/ of Fig. l.

In the several views the same parts are indicated by the same letters.

A represents a vertical frame supporting the series of vertical shafts B, (here shown as live in numbcr,) these shafts being on a line and jonrnaled to the frame, as shown, and cach having a gear-wheel, O, at the top. A horizontal shaft, D, runs along the top over the frame and over the center of the shafts B. On this horizontal shaft are the pinions E, meshing into the gear-wheels. O11 the lower ends of the several shafts B are the cranks F, with the wrist-pins G, to which are attached the rods II, (shown in Fig. 8,) each rod leading to and operating the pumping machinery of a well. The cranks F on the several shafts are adjustable as to their relative positions, so that the rods H are drawing on the wells alternately, thus equalizing the strain on the motive power (which is communicated through the medium of the shaft D) and the wells balance7 or the fall of the rods in one portion of the wells helps to lift the rods in the other portion. The cranks, of course, lnay be set at anyl relative angle with each other, so that the rods will be drawn upon alternately in whatever direction they may run, whether all to one side or on both sides. This will obviate the necessity of setting the transmitter in the center of the group, as in other devices used for a similar purpose. Another advantage which I claim for my device is that by chang ing the relative lengths of the cranks F a longer or shorter stroke may be given to some of the wells in the group if desired, or by varying the size ofthe gear-wheels Oa more rapid motion may be given to some ofthe wells than to others.

I have here illustrated my device as with the vertical shafts B all on one line and operated by pinions on one shaft. It is obvious that they may be placed in two lines with two shafts, or in any other requisite form, provided that the driving-shafts are connected together and all driven by one motor; also, the shafts are shown as having the power applied at the top and the crank at the lower end. rIhis may be reversed without affecting in any way the noveltyV of my device.

I make no claim to the device of balancing wells to lessen the motive power required, as that is old. Neither do I claim the device of a single vertical shaft with wrist-pins or ecceutrics as a device for operating pump-rods, as that is also old.

Vhat I do claim as my invention is- A series of vertical shafts set in a Vfixed frame, each shaft'connected directly by gearwheels with the motor-shaft and each shaft having a crank and wrist-pin, to which is attached a Arod running to and connected with the pumping machinery of one of a group of oil or Artesian wells, all the above-named parts in combination, substantially as shown, and for the purposes herein set forth.
